The upper end of each door is Wound upon a drum, the door 14 on the drum29 above the roof 13 of the car, and the door. on the drum 39 positionedin the roof construct-ion of the car. The doors 14 and 15 are arrangedto pass over the drums upon which the same are to be Wound and thenaround drums 31 and 32 respectively in the rear of the first mentioneddrums, before returning to said first mentioned drums. The curvedelongated head of the first section of each of the doors is received inthe drums 29 and 30 by passing thro-ugh longitudinal slots 33 therein.It Will be noted that when the drums 29 and 30 are rotated in aclockwise direction the doors 14 and 15 respectively Will be drawnupwardly and Wound thereon after passing around the drums 31 and 32respectively.

Y The drums 29, 30, 31, and 32, are mounted upon shafts 34, 35, 36, and37 respectively, Which have their opposite ends attached to supportingmembers 38. The members 38 that support the drums 29 and 31 are securedto a slightly inclined plate 39 positioned upon the roof of the car,While the supports for the drums 30 and 32 are at- 7 tached to theopposite side of a metallic 29 and 30 are rotated, the drums 31 and 32respectively Will be rotated in the same direction and at the samespeed, Which will cause the Winding of the door 14 on the drum 29 andthe door 15 on the drum 30.

The drum 29 is slightly longer than the remaining drums and has anothersprocket 46 thereon and secured thereto from which a sprocket chain 47extends to a sprocket 48 carried by the shaft 35. The sprocket 48 isloose on the shaft 35 and has a clutch face 49 on one side thereof forengaging a like clutch face 50 carried by a Worm gear 51 which is alsocarried by the shaft 35, said Worin gear having means connectedtherewith for rotating the same, Which means Will be described in detailas the deseription proceeds. The opposite side of the sprocket 48 has anannular recess 52 therein which receives an annular flange 53 carried atone end of a collar 54 slidable on the shaft 35 but fixed theretoagainst rotation. The flange 53 is positioned in the recess 52 forrotary movement yet retained therein by a ring member 55 secured to thesprocket 48. The collar 54 has a clutch face 56 arranged to engage asimilar clutch face 57 provided on one end of the drum 30. An annulargroove 58 is provided in the collar 54 which receives inwardly directedpins 59 carried by a yoke 60 on one end of a slidably mounted L-shapedlever 61. It Will be noted that When the lever 61 is shifted to engagethe clutch faces 49 and 50, the Worin gear 51 Will rotate the "i drums29 and 31 due tol the sprockets 46 and 48 and sprocket chain 47, andthat when the clutch faces 56 and 57 are engaged the drums 30 and 32will be rotated as the Worm gear 51 rotates the shaft 35 which Will routate the collar 54 upon Which the clutch face 56 is arranged.

ln order to rotate the Worm gear 51 a Worm 62 carried by a shaft 63meshes With said Worm gear, said shaft having a bearing 64 for one endthereof mounted on one of the supports 38, While the opposite end of theshaft 63 passes through a bearing 65 and opening 66 carried by andextending through the Wall 10 respectively. Attached to the lastmentioned end of the shaft 63 is a pair of universal joints 67 which arein turn connected to a vertical shaft 68 mounted for rotation in abearing 69 carried by the Wall 10. The lower end of the shaft 68 isreceived in a casing 70 arranged adjacent the floor 12 of the car, andhas a beveled gear 71 thereon Which meshes with a like gear 7 2 carriedby a bearing member 73 through which the shaft 68 extends. Secured tothe gear 72 is a crank handle 74 for transmitting rotary movement to thebeveled gears 72 and 71 through the shafts 68 and 63 and to the Wormgear 51. The casing has a slot 75 therein, While the member 73 isrotatable on the Vshaft 68 so that the handle 74 may be swung away fromthe Wall 10 When it is desired to rotate the drums for raising orlowering the door 14 or door 15.

loo

To prevent unauthorized persons from opening the doors, a keeper 76 issecured to the Wall 10 by bolts, rivets, or the like, said keeper havinga pair of parallel spaced lugs 77 projecting therefrom between which thecrank handle 74 is received when it is desired to lock same againstoperation. A headed pin 78 is then passed through a pair of aligning`openings, one in each projection, and a sealing device 79, such as thatcommonly used for sealing railroad cars, is passed through an opening inthe loWer end of the pin.

The lower end of the L-shaped lever 61 projects through a slot 81 in theWall 10,
